[Frost] poster and talk for Gordon

[Dave Ireland]

Hi Natalie,

Nice slides and poster, but I am a little concerned with values you are 
still getting for Target asymmetry. Your results for T are not 
consistent with GRAAL, but they are also not consistent with g8!

The formula you cite in slide 6, is valid only if there is no recoil 
information. If you use any of the decay products of the Lambda (pion or 
proton) to identify your events, you cannot help but be sensitive to 
recoil polarization and anything that depends on it. With circular beam 
polarization, transverse target polarization and recoil information, you 
are sensitive to 11 observables! You need to fit for all of them 
consistently.

Even if you pick out the cosine moment, there are other terms in the 
product which we know to be sizeable. For example Ox is large in the 
region you cover. That could be the origin of the discrepancies you observe.

Cheers,

Dave
